Photosynthesis

The reactants of photosynthesis are carbon dioxide, water, and light energy. Carbon dioxide is absorbed from the air, water is taken up through the roots, and light energy is captured by chlorophyll in plant cells to drive the process of photosynthesis.

Root hair cells are found underground, where there is no light. Chloroplasts help the process of photosynthesis. As there is no light, no photosynthesis takes place so chloroplasts are not needed.

there are many things that affect photosynthesis the main 2 are carbon dioxide levels and light. pottaisium hydrogencarbonate is sometimes added to the water because it provides carbon dioxide this is needed for photosynthesis. Light intesity is the biggest factor the more light intensity the more oxygen the plant produces

Photosynthesis produces starch which is stored as glucose, if the plant cannot photosynthesis for any reason it turns to its glucose/ starch storage and uses it in the plant.

Photosynthesis is a crucial process for plants as it allows them to convert sunlight into energy, in the form of glucose. This energy is essential for the plant to grow, develop, and carry out its daily functions. Photosynthesis also releases oxygen as a byproduct, which is vital for sustaining life on Earth.

Water is split in the light reactions of photosynthesis to provide electrons for the photosynthetic electron transport chain. This process releases oxygen as a byproduct. Additionally, water molecules help maintain the balance of protons and electrons within the thylakoid membrane during the light reactions.

It takes place in the stoma

The concentration gradient of protons is potential energy and is harnessed by an enzyme called ATP synthase. ATP synthase converts the potential energy of the proton concentration gradient into chemical energy stored in ATP (the process is called chemiosmosis).

So without the protons, no ATP would be made, and therefore no light reaction would occur.

Glucose and oxygen are used up during respiration.

A leaf obtains water through the process of transpiration, where water is absorbed by the roots from the soil and transported to the leaves through the xylem vessels. Once in the leaves, water is used in various metabolic processes and is also lost through small openings called stomata during transpiration.

6 carbon dioxide molecules and 6 water molecules.

Water + Carbon Dioxide = Glucose (Plant sugar)

12 molecules of water are used in the reaction but 6 of them are reformed at the end of the reaction. it is not that 6 of them are used and 6 are given out. all 12 are broken down but only 6 of them are reformed into water at the end.

They produce glucose and oxygen. Oxygen is given off as a gas.

In photosynthesis, carbon dioxide and water are used to produce glucose and oxygen. In cellular respiration, glucose and oxygen are used to produce energy (ATP), carbon dioxide, and water. So, carbon and oxygen are elements that are cycled through both processes.

Oxygen is the element produced after photosynthesis.

Photosynthesis: Photosynthesis is a process that converts carbon dioxide into sucrose, using the energy from sunlight.

Energy conversion: Energy conversion is the process of transforming energy from one form into another. for example Potential energy to Kinetic energy, etc..

Rubisco (ribulose-1,5-bisphosphate carboxylase/oxygenase) is an enzyme that plays a key role in photosynthesis by catalyzing the first major step in carbon fixation, where it combines carbon dioxide and ribulose-1,5-bisphosphate to form 3-phosphoglycerate. This reaction helps plants convert atmospheric carbon dioxide into organic compounds that can be used for growth and energy production.

Plants require carbon dioxide, water, and sunlight to carry out photosynthesis. These materials are essential for the process of converting light energy into chemical energy in the form of glucose, which is used as food for the plant.

Carbon Dioxide

Oxygen (O2) and glucose (C6H12O6)

You can look at the overall reaction of photosynthesis to determine the answer

6CO2 + 6H2O ---> C6H12O6 + 6O2

(reactants) ---> (products)

The world's estimated population is 7.4 billion. We all breathe out. In our breathing out is carbon dioxide.

The US publisher Ward's estimates there were 1.015 billion motor vehicles in use in the world in 2010, including cars, heavy duty trucks; and buses (but no off-road vehicles or heavy construction equipment). All these machines (and more) on average using just one gallon of gasoline produces 18.07 pounds of carbon dioxide.

About 22.38 pounds of CO2 are produced from burning a gallon of diesel fuel.

Experts estimate there are over three trillion trees on Earth, all of which crave CO2 in photosynthesis.

Experts estimate there are 390,900 TYPES of KNOWN plants, of which approximately 369,400 are flowering. There are thousands of unknown / unidentified species and about 2,000 identified each year. All green plants NEED CO2 for photosynthesis.

According to NCS University, "A tree can absorb as much as 48 pounds of carbon dioxide per year and can sequester 1 ton of carbon dioxide by the time it reaches 40 years old."

As you can see, trees and plants need to be present, alive, and prospering just to keep up with human production of CO2 per day!

Note: These numbers do not include how many trees are cut down each year. It does not include how many plants are destroyed, nor air pollution from slash and burn agriculture.

all plants undergoe photosynsthesis its the reaction to water and carbon dioxide to create oxygen which is essentail to all life

The oxygen atoms in O2 produced during photosynthesis come from water molecules (H2O) that are split during the light-dependent reactions in the chloroplasts of plant cells. This process, known as photolysis, releases oxygen as a byproduct.

Animals and plants both synthesize fats and proteins from carbohydrates; thus glucose is a basic energy source for all living organisms.

The oxygen released (with water vapor, in transpiration) as a photosynthetic byproduct, principally of phytoplankton, provides most of the atmospheric oxygen vital to respiration in plants and animals, and animals in turn produce carbon dioxide necessary to plants.

Photosynthesis can therefore be considered the ultimate source of life for nearly all plants and animals by providing the source of energy that drives all their metabolic processes.
